Got Aphids? Here’s How to Handle Those Pesky Pests

1. Blast with Water

• Use a strong spray of water from a garden hose to knock aphids off the plants. This is a simple and chemical-free method that works best in the early stages of infestation. Be sure to spray the underside of leaves where aphids tend to hide.

2. Introduce Beneficial Insects

• Encourage natural predators like ladybugs, lacewings and parasitic wasps, which feed on aphids. You can purchase ladybugs and beneficial insects from local nurseries and release them in your garden to naturally reduce aphid populations.

3. Neem Oil or Insecticidal Soap

• Apply neem oil or insecticidal soap, which are organic and safe for plants. These treatments are effective against aphids and other soft-bodied insects. Be sure to spray all parts of the plant, especially the underside of leaves.

4. Prune Infected Areas

• Remove heavily infested or damaged leaves, stems or branches. This not only reduces the aphid population, but also prevents further spread to healthy areas of the plant.

5. Companion Planting

• Encourage customers to plant species that repel aphids, such as garlic, onions and marigolds. These plants can act as natural deterrents, reducing the likelihood of infestations in the garden.

6. Use Yellow Sticky Traps

• Aphids are attracted to the color yellow. Placing yellow sticky traps around the garden can help monitor and reduce aphid populations.

7. Avoid Overfertilizing

• Overfertilizing plants, especially with nitrogen-rich fertilizers, can encourage tender new growth, which is more attractive to aphids. Advise customers to use balanced, slow-release fertilizers to avoid excessive growth.

8. Introduce Natural Barriers

• Plants like mint, nasturtiums or chives can serve as natural barriers to aphids. Encourage your customers to grow these plants near susceptible crops to help keep aphids at bay.

9. Biological Control

• For large infestations, introduce biological control methods, such as using predatory mites or purchasing nematodes, which attack aphids. These are effective for long-term control.

10. Monitor and Act Quickly

• Regularly inspect plants, especially during the warmer months, and act as soon as any aphids are spotted. Early treatment can prevent infestations from getting out of control.
